Abstract

The utility model relates to an automatic grading device for cultured fishes, comprising a frame, a fixed separate grid which is formed by vertical or horizontal equidistant grid strips and a netting which is connected on the frame. The upper part of the netting is provided with a floater rope with a floater and the lower part of the netting is provided with a sinker with a sinker. In order to increase the strength, at least one reinforced beam which is vertical to the grid strips is fixed on the frame. The frame can be rectangle shape, circle shape or oval shape. The utility model with the construction can not injure the fish body with a high grading efficiency, and the utility model is an automatic grading device for cultured fishes.

Description

The automatic grading plant of cultured fishes
Technical field
The utility model relates to a kind of automatic grading plant of cultured fishes.
Background technology
Along with the maximization of fish culture net cage, the cultured output of single port net cage can reach more than 20 tons, and the fry of putting in a suitable place to breed reaches 1.5~4.0 ten thousand tails.Because bait throwing in can't be evenly and fish qautobiology difference, cause the interior shoal of fish growth rate difference of net cage.After culturing after a while, individual specification difference is very big.In order to improve the culture benefit of large-scale fish culture net cage better, must be according to the specification size of fish body, with fish and time stage, the close shoal of fish of specification is placed in the same net cage cultures, help the even growth of fish.On the other hand, sell, also must carry out the specification screening to the shoal of fish of being cultured according to requirement of client to culturing successful fish.Usually the cultured fishes in net cage or the fishpond are mainly relied on artificial classification, not only the time long, labour intensity is big, and in sort process the fish body is caused to a certain degree damage and death.
Summary of the invention
The purpose of this utility model provides a kind of with low cost, simple to operate, and the demand of pressing the fish specification is effectively with the automatic grading plant of cultured fishes.
The utility model comprises the separate gate that framework and fixing grizzly bar vertical or that level is equidistant thereof constitute, and the etting that connects on the framework, and the corkline of band float and the sinker rope that the band sinker is arranged at the bottom are arranged at the top of above-mentioned etting.For gaining in strength, at least one buttress brace vertical with grizzly bar is set on the described framework is fixed on the framework.Described framework can be rectangle, circle or oval.
Description of drawings
Fig. 1, basic structure schematic diagram of the present utility model.
The utility model structural representation in Fig. 2, big degree of depth fishpond or the net cage.
The rectangular frame structure schematic diagram of Fig. 3, vertical grizzly bar.
The rectangular frame structure schematic diagram of Fig. 4, horizontal grizzly bar.
The oval frame structural representation of Fig. 5, vertical grizzly bar.
The circular frame structural representation of Fig. 6, vertical grizzly bar.
Wherein: 1. framework, 2. grizzly bar, 3. etting, 4. float, 5. corkline, 6. sinker, 7. sinker rope, 8. buttress brace.
Embodiment
The utility model comprises the separate gate that framework 1 and fixing grizzly bar 2 vertical or that level is equidistant thereof constitute, and the etting 3 that connects on the framework 1; Consider the effective expansion with above-mentioned etting 3, the top of above-mentioned etting 3 is provided with the corkline 5 of band float 4 and the sinker rope 7 that band sinker 6 is arranged at the bottom.
Consider the situation of the depth of water,, can strengthen the yardstick (on the degree of depth) of etting, as Fig. 2 for separate gate being unlikely to too greatly or too heavy.The etting of separate gate side prevents that fish from passing through, and suitable grid spacing allows small fish freely to pass through, and big fish can not pass through, thereby the shoal of fish can be separated automatically according to the specification size, the separate gate of vertical or horizontal grizzly bar and different grid spacings can separate the fish of variety classes and different size.As to porgy, perch, U.S. snapper, lefteye flounder etc.
Described framework 1 can be rectangle, circle or oval.
For increasing separate gate intensity and keeping the grid spacing constant, increase one or more buttress braces 8 on the separate gate, therefore on the described framework at least one buttress brace vertical with grizzly bar 8 is set and is fixed on the framework 1.As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6.
Utilize the reaction of fish to light, as the luminous effect that becomes, be not difficult lighting to be set in a side, also can quicken the separating rate of large and small fish.
The utility model fish classification efficiency height of constructing does not thus injure in the fish body again, is the automatic grading plant of cultured fishes.
